Step 1: Construct the cumulative frequency distribution. In principle, in order to compute descriptive statistics for grouped data we need to estimate a proxy for the values that belong to a certain class/interval, by computing the midpoint of the interval. You can use this calculator to compute the RMS voltage value in three simple steps: Input the peak voltage Select the waveform Click on the "Calculate RMS" button. n = 4. The formula for determining class intervals is as follows: Generally, 5 k 15. Absolutely irrelevant to your question, but I would suggest to use something like this for the actual computation: Difference with sum(x**2/len(x) is that in that case you construct np array and then let Python iterate over it as over any usual sequence and sum its elements, but if you do ((x**2)/len(x)).sum() or (x**2).sum()/len(x) the summation is done by numpy - it will be 30-50x faster this way. Convert acceleration to displacement using Equation (11), then convert the displacement units using Equation (10). P.S.
